Which organizations are cited as not recommending lead spot test kits?

• A. EPA only
• B. HUD only
• C. EPA and HUD
• D. Neither

Answer: (C)

Spot test kits aren’t reliable enough for deciding lead hazards. The EPA and HUD both discourage using these kits because they can give false negatives or positives depending on the surface, pigments, coatings, or contaminants present, and they don’t provide the quantitative information needed to determine hazard levels. Federal guidance favors validated methods like X-ray fluorescence (XRF) for in-place screening and certified laboratory analysis for confirmation, ensuring accurate identification of lead presence and concentration. Because of these reliability and validation concerns, both agencies do not endorse lead spot test kits.
